A long time ago, on a mailing list far away, I promised to send the SysV
interface script that I use with success; the supplied one is a bit, err,
basic...
Well, one thing led to another, and I quite forgot, so without further
ado, here it is (usual disclaimers):
#!/bin/sh
#
# This interface script drives a PC-attached printer via the SAMBA utility.
#
# This script is a gross simplification of the "official" SysV
interface
# script, whilst attempting to achieve much of the same functionality.
#
# Note the almost fanatical redirection of output; lpsched treats any
# output from this script as a problem with the request, and kills it,
# exit codes notwithstanding....
#
# In a previous life, it was distributed with the SAMBA software, but
# has since been hacked to the point of non-recognition.
#
# Dave Horsfall, FGH.
#
# clear out the unwanted parameters
copies=$4 # We want this one, but.
shift; shift; shift; shift; shift
pw="" # We *must* supply a password
smbclient=/usr/local/samba/bin/smbclient
lptell=/var/spool/lp/bin/lp.tell # Regrettably necessary
ping=/usr/sbin/ping
printer=`basename $0`
#
# Note the use of upper-case names.
#
case $printer in
prw1)
server=wpark1
server1=WPARK1 # SMB name
service='PICKING'
;;
esac
#
# PCs have a distressing tendency to be switched off; let's spare
# ourselves some heartache.
#
$ping $server > /dev/null 2> /dev/null
if [ $? != 0 ]
then
echo "The PC \"$server\", for \"$printer\", is not
reachable." | $lptell $printer
disable -r "$server not reachable" $printer > /dev/null
2>/dev/null
exit 129 # Anything > 128 will keep the job
fi
#
# If smbclient is handed a bad service name, it exits without reading,
# thus SIGPIPEing us.
#
# What about a test for the service name? Something like:
# smbclient -L $server | grep Printer | awk '{ print $1 }' -ne $service
??

i=1
while [ $i -le $copies ]
do

trap "exit 1" 13
